Original application filed October 17, 1919, Serial No. 331,350. Divided and this application filed February 9, 1920. Serial No. 357,114.

To all whom it may concern:

Be it known that 1, JOHN J. PETERSON, a citizen of the United States of America, residing at Steubenville, in the county of Jefferson and State of Ohio, have invented new and useful Improvements in Window- Cleaning Devices, of which the following is a specification.

This invention relates to cleaning devices, and more particularly to a device specially adapted for cleaning Windows and for similar purposes.

One of the main objects of the invention is to provide a power operated device of simple construction and operation by means of which particles of dust and foreign materials may be readily removed from window panes and collected, the means for removin the dust also serving to polish the panes. further object is to provide a device which may be readily applied to a handle so as to be operated b a driven member mounted on the handle. Further objects will appear from the detailed description.

In the drawings :-Figure 1 is a back view of the device.

Fig. 2 is an end view.

Fig. 3 is a transverse section taken substantially on line 33 of Fig. 1.

This application is a division of my appli cation Serial Number 381,350 for window cleaning device, filed October 17th, 1919.-

I provide a semi-cylindrical casing 1 in which is rotatably mounted a longitudinally extending roller 2 which may be formed of fabric or any suitable material well adapted for cleaning and polishing glass. This roller is provided with a shaft 3 the end portions of which are reduced and extend through the ends of the casing. A spur gear 4 is secured on one end of this shaft and meshes with a spur pinion 5 mounted upon a stub shaft 6 secured to the end of the casing, this pinion meshing with a spur gear 7 secured upon the outer end of a shaft 8 rotatably supported by brackets 9' secured to the casing 1. A bevel gear 10 is secured to the inner end of shaft 8 and meshes with a bevel gear 11 rotatably supported by a bracket 12 and connected by flexible shaft 13 to spur gear 14- rotatably supported by bracket 15, this bracket being carried by bow 16 the arms 17 of which are secured to the ends of casing 1. In cases where the window does not require washing, as where a light film of dust has collected upon the window pane, it may be readily cleaned by means of this device, the roller 2 acting as a bufling roller to clean and polish the surface of the glass. The particles of dust and other foreign material removed by the roller 2 from the window pane are discharged rearwardly through a rearwardly converging passage or throat 18 into a substantially cylindrical dust chamber 19 positioned rearwardly of the casing land provided with an-air escape opening 20 which is covered by a strip 21 of fabric of fine mesh.

To insure proper discharge of the dust particles into throat 18, the upper wall 18 thereof is extended to provide a baffle 22 which is inclined downwardly and inwardly of easing 1 and has its inner edge positioned closely adjacent to the periphery of roller 2.

As will be noted from Figs. 1 and 2, the lower ends of arms 17 of bow 16 are united to form a tapering member adapted to be secured in a suitable socket in a supporting member or handle, the gear 14 being driven by suitable means carried by this handle, as fully described in my copending application above referred to.

What I claim is:

In a device of the character described, a seini-cylimlrical casing provided with a rearwardly projecting throat member, a dust receiving casing supported by the throat member and in direct communication there with, said dust receiving casing being provided with an air outlet, a roller rotatably mounted in the casing axially thereof, and a baffle projecting from the upper wall of the forward end of said throat member to within a short distance of the periphery of the roller.

In testimony whereof I afliX my signature.

JOHN J. PETERSON.
